I may be asking a rather unintelligent question here, but... has anyone or is it possible to put a throttle body spacer on a marine engine? I know with trucks/suvs they are often added without any consequence and a slight HP/Torque/efficency gain. What would stop the same possible gains in a marine motor.

The only thing i can think of is the amount of air flow, however, a marine engine still has to have air inorder to cause combustion.

Whats all of your thoughts....

I dont have an MC but my motor is a GM 305 Block.

You would probably get a larger performance increase by cleaning your air filter / flame arrestor. They're gimmicks and don't work.

I gained a 5% increase in horsepower by greasing my muffler bearings.

Got you beat TX............15% fuel savings with my tornado. I plan to switch to a tunnel ram intake so I can run two and save 30%!

Yeah and while im considering that left handed screw driver to grease my muffler bearings, I had better check my running lights, they are running low on fluid!
